The reaction of ArPO(3)H(2) (Ar = 2,4,6-iPr(3)-C(6)H(2)) with Cd(CH(3)COO)(2).2H(2)O using various co-ligands such as methanol, dimethylformamide (DMF) and 3,5-dimethylpyrazole (DMPZH) resulted in the formation of tetranuclear assemblies [Cd(4)(ArPO(3))(2)(ArPO(3)H)(4)(CH(3)OH)(4)].3(CH(3)OH) (1), [Cd(4)(ArPO(3))(2)(ArPO(3)H)(4)(DMF)(4)].3(DMF) (2) and [Cd(4)(ArPO(3))(2)(ArPO(3)H)(4)(DMF)(2)(DM...

Azolium-2-thiocarboxylate zwitterion ligands have emerged as a promising class of compounds in the field coordination chemistry due to their unique structural features and versatile applications. These are characterized by positively charged azolium ring negatively thiocarboxylate moiety, making them capable forming stable complexes with various metal ions. One key aspects that make these attra...

The title coordination polymer, {[Cd(C8H4O4)(C14H14N4)]·C3H7NO} n , was synthesized by solvothermal reaction of metallic cadmium with the semi-rigid neutral ligand 1,4-bis-[(1H-imidazol-1-yl)meth-yl]benzene (bix) and the V-shaped benzene-1,3-di-carb-oxy-lic acid (m-H2bdc). The structure exhibits a pseudo-C-centring which is almost fulfilled by the polymeric metal complex but not by the solvent ...

Amide synthesis is one of the most crucial transformations in chemistry and biology. Among various catalytic systems, N-heterocyclic carbene (NHC)-based ruthenium (Ru) catalyst systems have been proven to be active for direct amides by sustainable acceptorless dehydrogenative Coupling primary alcohols with amines. Most often, these usually use monodentate NHC thus require an additional ligand o...

A fluxional bis-monodentate ligand, based on the archetypal shape-shifting molecule bullvalene, self-assembles with M2+ (M=Pd2+ or Pt2+) to produce a highly complex ensemble of permanently coordination cages. Metal-mediated self-assembly selects for an M2L4 architecture while maintaining ligand complexity. second level simplification is achieved guest-exchange; binding halides within cage mixtu...
